My sister was visiting so we took a trip up into the Cascades across the North Cascades Highway. Having traveled this way before, I had photographed some of the dams already. This time, we got a closer look at Diablo Dam. You can drive down to the dam and across the top of it to get to the facilities on the other side. The dam is wide enough for two vehicles to pass although that might not be obvious given the way some of the drivers behaved.
The spillways on either side of the dam look a lot bigger when you get close to it than is the case when looking from a distance. The chance to see it up close, given that so many of the dams in the mountains are rather inaccessible, was pretty cool.
